Companies increasingly use OneDrive, which is why Microsoft adds features like "Document collaboration and co-authoring." Working together with Office documents is very popular for users, especially with Excel and Word. However, once the feature is enabled, you might get the error message: "Server File Updated. A newer version is available". You will find numerous hints on the Internet about the error, but nothing helped my customer.
With my customer, it was clear. Once the feature "Document collaboration and co-authoring" was enabled, they got the error "Server File Updated. A newer version is available" as soon as they opened any Excel file out of OneDrive.
